Unit five graphing linear equations lesson seven graphing equations
Here is an example of graphing a linear equation:
Let's graph the equation y = 2x - 3.
To graph this equation, we can use a table of values or the slope-intercept form.
Using the slope-intercept form y = mx + b, we can see that the slope m is 2 and the y-intercept b is -3.
From the y-intercept, we plot the point (0, -3) on the graph.
Next, we use the slope of 2 to find another point. Since the slope is rise over run, we go up 2 units and right 1 unit from the y-intercept point. This gives us another point (1, -1).
Now, we can draw a straight line passing through these two points.
The graph of the equation y = 2x - 3 is a straight line with a slope of 2 and y-intercept of -3.
You can repeat these steps for other linear equations to graph them as well.
